Problem Solution
Machine starts but does not stop • Establish a move Preset
• Ensure brake functions properly using output test.
Machine stops out of position • Make sure the marker pulse is detected before brake outputs fire.
Display counts backwards • Reverse Encoder A, B, wiring.
Machine stops abruptly, not a soft stop • Turn down torque adjust potentiometer for Channel 1.
Machine stops but then restarts • Control may be responding to a start command. Check for
transient signals. Use the E-Stop feature described in "Additional
Features" to disable a start input.
Control appears to function perfectly but the actual • Check for slippage between the encoder and the manual items.
error is greater then the display indicates.
Display not counting • Check encoder connections. If good connections exist, send
encoder for repair.
Control accumulates too many counts. Home or • Check Display Scaling, page 10, and check for electrical noise,

not occurring. Use Output Test (line 30) to verify performance.
System does not operate and fails diagnostic • Return unit for repair, call an Authorized Warner Electric
Tests 1,3, 4, 5 or 7. Reference page 15. Distributor.
System stops, but does not fire outputs. • Lower zero speed window (line 19) to minimize effects of
encoder "bounce" caused by vibrations.
'Ref' light not illuminating every cycle. • A lower resolution encoder may be needed. Call factory for more
information.
Error Codes
If an error message appears
• Disconnect power to CBC-1000 momentarily and error should
clear. Press to clear error code.
Error Code 2 - Low Line Voltage. • Correct line voltage. Press to clear error code.
Error Code 3 - Feedback too fast. • Reduce encoder resolution and/or speed to keep encoder feed-
back less than 20,000 PPS. Press to clear error code.
Error Code 4 - Process Time fully utilized • Reduce encoder resolution or consult factory. Press to
clear error code.
